That is, according to recent research: Study participants between the ages of 60 and 90 were divided into groups; some were given packets of structured activities –  informative magazines, word and crossword puzzles, classical music – while others learned quilting and/or professional photography software. The result is good news for anyone who agrees that learning new skills is also a good way to stay happy. Read more on Marketwatch.com.

And finally… A follow up to a piece we ran some time ago about Dr. Mehmet Oz’s advice; back in January 2013 we cited a Slate.com critique of Dr. Oz‘s recommendations, especially in light of the fact that Oz was chief scientific adviser for RealAge.com (O’s company has since bought that website). Well, last month John Oliver skewered Oz in a segment of his TV show Last Week Tonight, and that video has since gone viral on YouTube.
